氣相色譜儀測(cè)定ppb級(jí)痕量CO2
1962年K.Porter和D.H.Volman提出轉(zhuǎn)化法,將樣品中的CO經(jīng)鎳觸媒催化加氫轉(zhuǎn)化成CH_4,用氣相色譜儀氫火焰離子化檢測(cè)器(FID)檢測(cè)。目前這種方法已被廣泛用來測(cè)定微量CO和CO_2。
ppb級(jí)痕量CO2含量測(cè)定,即使采用FID+甲烷轉(zhuǎn)化爐也很難準(zhǔn)確測(cè)定,況且甲烷轉(zhuǎn)化爐還存在轉(zhuǎn)化率和鎳觸酶的失效問題,為了解決這一難題,滕州市浩瀚色譜儀器技術(shù)服務(wù)有限公司,與時(shí)俱進(jìn),以科學(xué)發(fā)展為指導(dǎo),在王曉瑩經(jīng)理的帶領(lǐng)下,依托翔鷹分析技術(shù)研究所,色譜工程研究所,分析與測(cè)試中心3個(gè)科研單位,經(jīng)過大量實(shí)驗(yàn),研發(fā)出靈敏度氣相色譜儀測(cè)定ppb級(jí)痕量CO2,CO2含量可以檢測(cè)到0.2ppm以下,測(cè)量數(shù)據(jù)準(zhǔn)確。

Determination of ppb level trace CO2 by ultra-high sensitivity gas chromatograph
In 1962, K. Porter and D. H. Volman proposed a conversion method, in which CO in the sample was converted into CH 4 by catalytic hydrogenation of nickel catalyst, and detected by a gas chromatograph with a flame ionization detector (FID). At present, this method has been widely used to determine trace amounts of CO and CO_2.
It is difficult to determine the content of trace CO2 at the ppb level even if the FID+ methane reformer is used. Moreover, the methane reformer still has the conversion rate and the failure of nickel catalase. To solve this problem, Tengzhou Haohan Chromatography Instrument has limited technical services The company is advancing with the times and guided by scientific development. Under the leadership of manager Wang Xiaoying, relying on three scientific research units, Xiangying Institute of Analytical Technology, Chromatographic Engineering Institute, and Analysis and Testing Center, after a large number of experiments, they have developed a super high Sensitivity gas chromatograph measures ppb level trace CO2, CO2 content can be detected below 0.2ppm, the measurement data is accurate and reliable.
